That would be the pilot bearing that runs inside the main drive gear. It should be possible to use a gear puller to remove the old one. It has been a while since I looked at one that close.
When you install the new or used main drive gear and clutch shaft assembly, the bearing preload for the transmission main shaft must be adjusted. If the main shaft is running too tight, you will need to remove some of the shims that are behind the rear bearing retainer. The only way to do that is to separate the transmission from the rear end housing. It is good to have a supply of the shims handy, so you will have the right number and thickness needed. That is the way the manual says to do it. Shims go behind the rear bearing retainer. Looking at the photos in the manual If the main shaft is too tight, I cannot tell why it wouldn't be ok to add a shim behind the front bearing retainer.
